Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, the main frame of the machine comprises a pair of upright side supports or standards 30 and 31 connected by suitable bracing rods 32 and provided at one end with extension members 33 and 34 secured thereto and having raised platforms 35 and 36 formed thereon, the said wardly of the supports, and a flat longitudinal shelf portion resting on and secured to the supports. Within the channels of the trackways, there are reciprocatingly mounted slide bars 40 and 41 aving antifrlction rollers 42 disposed within the channel, and.

adapted, as will hereinafter more fully be pointed out, to carry the wrapper and can transference means to vand fro.

The wrappers A are supported upon a ta ble 43 disposed at the upper end of a screw 44 movable through the threaded bore of a worm gear 45, rotatably disposed in the hearing portion 46 of a crosspiece 47, connected at its ends to the supports 30 and 31. A transverse shaft 48 is journaled in brackets 49 and50 formed upon the erosspiece 47 and in bearings 51 and 52 formed in the supports 30 and 31, and having mounted thereon, a worm meshing with the gear 45 and adapted upon being turned to slowly turn the saidgear and thereby gradually and slowly cause the table to be raised as the wrappers are removed therefrom, the successlve upward movements of the table being equal to'the thickness of one wrapper. Upon one end of the shaft 48, there is provided a ratchet gear 53, and at the side of the same, an arm 54 provided with a spring pressed'pawl 54 engaging the ratchet, the endof the arm being connected by a connectin rod 55 to a crank arm 56 provided upon 51c end of a shaft 57 journaled in the supports 30 and 31, and adapted to continuously rotate from the transmission means as will hereinafter more fully appear.

The stack of wrappers is guided and confined at its forward side by means of bars 58 and 59 supported at their upper ends upon a transverse shaft 60 journaled in the supports 30 and 31 and disposed below the upper end of the stack and provided at their lower end with forked portions '61 engaging over the shaft 48. At its rearward side the stack is engaged by bars 62 supported at their upper ends in brackets 63 mounted upon a shaft 64, and fixed against rotation by means of set screws 65, the ends of the said shaft being. adjustably engaged in slots 66 and 67 provided respectively in the extension members 33 and 34. There are also mounted upon the shaft 64, brackets 68, in the c lindrical portions 69 of which there are isposed vertically arranged pressure members '70, the lower end thereof being capped with rubber or other suitable frictional material as at 71, springs 72 disposed between the lower capped ends of the brackets yieldingly engaging the members with means 39 there are mounted standards 76 and 77 having tables 78 and 79 provided thereon and upon which there is supported a transverse platform 80. A similar platform 81 is supported between the tables 35 and 36, and a third and longitudinally disposed platform 82'is supported at its ends upon the tables 35 and 78. Upon the respective platforms 80, 81 and 82, there are mounted paste boxes 83, 84 and 85. The platform 81 is adjustable by means of slots 81 and bolts 81, while the platform 82 is similarly adjustable by slots' 82 and 82 to permit'of the paste boxes being adjusted to different sized wra pers.

T e box 83 comprises side members 86 and 87 havin bearing portions 88 at their forward en s in which are journaled therespective shafts 89 and 90 of a paste feed roller 91, and a rotarypaste transference member consisting of an arm 90 fixed to the shaft 90 and carrying a'flexible brush member 90 of rubber or other suitable material and adapted upon rotation to successively receive paste from the roller 91 and impart the same to the edge of the paper as at a Figure 1. A ar 92 is provided upon the shaft 89 which meshes with and drives a smaller gear 93 provided upon the shaft 90, the shaft 89 extending from the paste box through a supporting bearing bracket 94 mounted upon the table 79, the said shaft being provided at its end with a sprocket 95 driven by a suitable chain connection hereinafter referred to, from the transmission means. The floor 96 of the paste box is in yielding enga ement at its forward end with the surface 0 the roller 91 and may be regulated relatively to the surface of the said roller by means of a plurality of elongated set screws 97 hearing at their forward ends upon pivotally mounted shoes 98 in turn to bear upon and move pins 99 engaging the flexible end of the floor. The flow of paste to the surface of the roller 91 may thereby be accurately regulated both as to thickness and location.

'The paste box 84 is similar in construction to the box 83, the driving shaft 100 carrying the roller 101 and the gear 102 which meshes with and drives the smaller gear 103 upon the shaft 104 carrying the rotatable paste transference member 105 extending through a supporting bearing bracket 106 supported upon the table 36 smaller ar 111 provided upon the shaft 112 of e paste transference member 113,

and upon the shaft 108 there is also provided a beveled gear 114 which meshes with a beveled pinion 115 mounted upon one end of a shaft 116 journaled in a bracket 117 provided upon the side of the box 85 and provided at its other end with a sprocket gear 118 driven by a chain connection hereinafter referred to hem the transmission means.

At the forward ends of the slidebars 40 and 11, there are mounted journal boxes 119 each having a pair of sockets in which are respectively mounted the ends of a non-rotatable shaft 129 and a rotatable shaft 121. Upon the non-rotatable shaft 120 there is mounted a pair of gripping fingers 122 ex tending beneath and adapted to cooperate with a pair of gripping fingers 123 to grip the wrapper 1n the forwardly moved position of the slide bar as indicated in Figures 1 and 5, the said gripping fingers being preferably capped at their ends with rubber or the like. An arm 124 mg a roller 125 is provided upon the shaft 121 and engages at the ends of the forward and rearward movement of the slide bars, the respective tripping cams 126 and 127 to cause the fingers to grip and release the wrapper, the rs being retained in their moved positions by means of leaf springs 128 secured to collars 129 on the non-rotatable shaft 120, and be upon fingers 130 provided upon collars 131 mounted on the roilataglle shaft 121, the spran' gs act' upon t e ers at either side of the de a d center formed by the afls of rotation of the shaft.

In order to position the wrapper to be properly gripped by the fingers, there are provided at each side of the stack of wrap pars upon the hams slideways 132 and 133 angularly disposed and adjustable as to their angle by means of the circumferentially slotted base plates 134 secured to the frame by bolts 135 and 136. In the channels 137 and 138 respectivelyof the slideways there are mounted slide-rods 139 adapted to be reciprocated by crank levers 140 and 141, en ga g pins 142 provided upon the rods at their slotted ends 1413 and 144, the said levers being pivotally mounted at 1 16 and 147 upon posts 148 and 119 formed upon the frame and ha their short arms connected by rods 150 and 151 respectively to levers 152 and 153 pivotally mounted at 154 and 155 upon the frame, springs 156 and 157 bein connected between'the inner arms of the sai levers 152 and 153 and the points 158 and 159 secured to the frame, and normally holding the slide-rods in their retracted positions.

Upon the slide bars 40 and 41 there are secured brackets 160 and 161 pivotally supporting trip fingers 162 and 163, the said finthe path of the inclined ends. of the levers 152 and 153 and held against stops 164 and 165 by means of springs 166 and 167. -During" the rearward movement ofthe slide bars, the trip fingers 162 and 163 carried thereby pivot during their engagement with the levers 152 and 153 and ride freely over the same. When the slide bars move forward however, the trip fingers are held rigid during engagement with thelevers 152 and 153 and gers having inclined ends and projecting in cause the same to be swung about their piv ots thereby reciprocating the slide-rods 139.

The slide-rods 139 are jointed at 168 (Figures 6 and 7) and during their projecting movement first swing downwardl into engagement with the wrapper an continue moving toward each other in engagement with the wrapper, causing the same to be humped at its intermediate portion. For this purpose a projecting arm 169 is provided uponthe forward end of the slideway and engages the under surface of the forward portion of theslide-rods, the said sliderods having at said under surface an inclined surface 170 which causes the same to be raised and lowered. At the forward end of the rods 139 there are provided caps provided with an inset of rubber or other suitable gripping substances 181 provided with a threaded shank 182 engaging the end of the rod to enable adjustment.

When the wrapper is in its humped positiou, a pair of spacing fingers 183 and 181 having wedge shaped ends 185 and fixedly mounted upon the transverse rock shaft 60, enter beneath the wrapper and hold the same raised so that it may be gripped at its edge by the gripping fingers 182 and 183. .As indicated in Figure 5, the shaft is rocked by means of an arm 187 fixed thereon and provided at its end with a roller 188 engaging a cam 189 provided upon the shaft 57.

At the end of the machine opposed tothe stack of wrappers, there is provided an extension frame comprising a pair of tubular standards 190 and 191 havin circular bases 192 and 193 and provided with telescoping posts 191 adapted to be fixed in their position by means of set screws 195. Collars 196 and 197 are secured to the posts 194 and longitudinal rods 198 and 199 are screwed thereon at one end as at 200 and at their other ends are screw threaded at 201 and adjustably engaged with a transverse crosspiece 202 connecting the supports 39 and 31, lock-nuts 203 fixing the position of the said rods. Upon the rods 198-a'nd 199 there are supported, in spaced relation, inverted l3- shaped supports 204 and205. carrying a longitudinal platform 206 disposed beneath and supporting the upper part of a feed belt extending over rollers 208 and 209 mounted.

' belt there are provided longitudinal guides 217 and 218 between which the can or other articles B to be wrapped are fed, the foremost can being positioned preparatory to being removed by means of yieldable holding fingers 219 and 220.

Upon the slide bars 40 and 41 there are secured upstanding standards 221 and 222 between which there is supported a shaft 223. Upon the shaft 223 there is supported a fixture 224 extending downwardly and provided with a gripping face 225 adapted to engage the can at one slde. A bracket 226 is also secured upon the. shaft 223 and pivotally supports a lever arm 227 provided at one end with a gripping face 228 adapted to engage the can at the other side thereof from the face 225, and provided at its other end with a roller 229 adapted to respectively engage trip cams 230 and 231 at the ends of its forward and rearward movement to release and grip the cans, a spring 232 adapted tohold the leverin gripping engagement with the can. When the arm is moved as indicated in Figure 3-to release the can by engagement with the cam 230, a snap spring 233 engages beneath the arm and holds the same in its disengaged position until the roller engages the cam 231 whereupon the force of the snap spring 233 is overcome and the arm is caused to grip the can. In operation the feeding of the can and wrapper into superimposed relation, is as follows:

The gripping fingers 122 and 123 upon rearward reciprocation of the slide bars 40 and 41, remove a wrapper from the stack and deposit it upon the table 234 against limiting stops 235 and 236. Alternately with the gripping of the wrapper, the can gripping arms 224 and 227 grip the forward can and upon forward reciprocation of the slide bars, carry the same over the previously deposited wrapper and dro it thereon as indicated in Figures 2 and 3, t e forward movement of the-slide bars overcoming the holding force of the holding fingers 219 and 220. p

The slide bars 40 and 41 are reciprocated anem a connected by a rod 245 to a crank lever 246.

mounted at one end of a shaft 247, the said shaft being provided at its other end with a gear 248, meshing with and driven by a gear 249 mounted on the shaft 250, and which in turn is driven by a pinion gear 251, provided upon a driving shaft 252' which may be connected to any suitable source of motive power.

Upon the shaft 250 there is provided a sprocket gear 253 connected by a sprocket chain 255 to a sprocket gear 256 provided upon a shaft 257 journaled in the supports 30 and 31, and rovided with a gear 258 meshing with and driving the gear 259 of a transverse shaft 260 also journaled in the supports 30 and 31 and provided with sprocket gears 261 and 262, the former being connected by a sprocket chain 263 to the sprocket gear 118 for driving the pasting means adapted to impart the strip of paste 0 to the wrapper, while the latter is connected by a sprocket chain 264 to the sprocket gear 95 for driving the pasting means 83 for impjarting the paste as at a to the wrapper.

pon the shaft 260 there is provided a sprocket gear 265 connected by a chain 266 to the sprocket 107 for driving the pasting means 84 for imparting the paste as at b to the wrapper. The shaft 57 is driven b means of a sprocket gear 171 upon the sha 260 connected by a chain 172 to a sprocket gear 173 mounted on the shaft 57.

The shaft 250 is provided with asprocket gear 267 connected by a chain 268 to a sprocket gear 269 provided upon a shaft 270 journaled in the supports 30 and 31 and having thereon a pinion 271 meshing with and driving a gear 272 provided upon the shaft 210 for driving the feed belt 207.

Disposed transversely beneath the frame and at each side of the table 234 there are provided two continuous driving chains 273 and 274 extending over sprocket wheels 275 provided upon shafts 276 and 277 and 278 and 279 journaled in bearing brackets 280 and 281 mounted upon the respective supports 30 and 31, the said chains passing through openings 282 and 283 and 284 and 285 formed in said supports.

The shaft 277 is provided at one end with a beveled pinion 286 meshing with a beveled gear 287 mounted at one end of a shaft 288 journaled in the supports 30 and 31 and provided at its other end with a gear 289 meshing with the gear 249 of the shaft 250 and adapted to be driven thereby from the driving pinion 251 to cause the chain to travel in the direction of the arrows (Figure 3) ing portions 299 of crosspieces300 and 301 extending between the supports 30 and 31,

the downwardly depending portions of the said t having springs 302 coiled thereon, and aring at their ends upon the under sides of the portions 299 and upon collars 303 provided on the ends of the said posts.

The crosspieces 300 and 301 are respec-.

\ tively'provided with longitudinally disposed bearmgs 304 and 305 in which is journaled a shaft 306 adapted to be rotated from the sprocket wheel shaft 278 b v sprockets 307 and 308 respectively provi ed on the said shafts and a continuous -chain connection 309, a cam 310 being provided on the shaft 306 enga ing-a roller 311 mounted'upon the under si e of the platform 293 and adapted to raise and lower the said platform, the cam being of such design that the platform is in its raised position during a quarter of a revolution of the shaft 306 and in its lowered position during a quarter of a revolution.

Beneath the table 234 there are mounted upon supports 312 and 313, and between the chains 273 and 274, supporting shelves 314 and 315 disposed at each side of an opening 316 'into which the platform 293 descends with its upper surface flush with the upper surface of the said shelves, this movement causing the end portions of the wrapper A to be bent upwardly at each side of the can B, indicated in Figure 13.

Supported upon and extending between the. chains 273 and 274, there are provided a series of carriers (Figures 8 and 9), each of the said carriers consisting of a crossbar 317 mounted at its ends upon blocks 318 and 319 secured respectively to one of the links of the chains, the said bar being provided with a forwardly projecting central portion 320 in which there is 'rotatably mounted a pusher roller 321.- A plate 322 is disposed upon the upper side of the bar 317 being provided with a raised forward end portion y a spring the un 323 extending above and having its forward edge in front of'the roller 321 in one position thereof. The plate 322 is provided with slots 324 and 325 engaged by guide pins 326 provided on the bar 317, and at its rear end is bent downwardly as at 327, the said portion 327 being held in engagement with cam fingers 328 provided on the rock shaft 329 journaled in bearings 330 of the bar 317 by 331 extending between a lug 332 ater side of the plate and the said downwardly bent portion. Upon one end of the. shaft 329 there is provided a trip lever '333 which as its upper arm comes into engagement with a trip pin 334, moves the cam 330 into the downwardly extending position shown in Figures 3 and 9 in which position the end of the late 322 extends beyond the periphery of t e roller 321, and I -which when its lower arm engages a trip pin 334 moves the cam into its raised position (F1gure 3) retracting the plate 322 so that its forward edge is rearwardly of the periphery of'the roller for a purpose which willbe presently more fully pointed out.

' As the carrier comes into contact with the can disposed upon the platform 293 in its lowered position, the u turned wrapper at one side is engaged by the projected portion 323 of the plate 322 and is thereb folded over the top of the can as indicate in Figure 15 and as the can is moved'on to the 'shelf 314, by the movement? of the carrier,

the downwardly bent portion 291 of the table 234 folds down the upturned side upon which the can passes, the pressure of the 341 and 342 bearing thereon and beneath rollers causing the upper folded over portion of the wrapper to be pasted down upon the lower folded over portion as indicated in Fi ure 1?.

pair of supports 343 and 344 are secured to the ends of the brackets 280, being braced at their outer ends by rods 345 and 346 and upon their upper sides there are mounted standards 347 and 348. Upon the inner sides of the said standards 347' and 348 there are provided brackets 349 and 350 in which are mounted pivoted frames 351 and 352, rollers 353 and 354 being suitably mounted respectively in theouter ends of the frames while their inner ends are yieldably held against stops 355 and 356 by springs 357 and 358, the outer roller end adapted to beswung downwardly when pressure is applied thereto. The surfaces of the said rollers are in line with the upper surface of the shelf 314, whiletheir peripheries extend within the end extremities of theran to support the same thereon.

a An extensible shelf 359 is provided in continuation of the shelf 314 being slidably mounted upon a support 360 secured to the support 30, a slot 361 being provided in the said support which is engaged by a guide lug 362 secured to the under side of theshelf, a spring 363 connected to the said lug nor- -mally holding the said shelf in its rearward position with one end abutting the end of the shelf 314 while its other'end terminates above the axis of the sprocket shaft 276. As the can reaches a osition on the shelf 359 with shown in Fi re 8, a lug 364 on the under .side thereofis engaged by a finger 365 carried :by the chain and thereupon the shelf is moved-forwardly with the chain, deposit- -ing- .t he can upon the rollers 353 and 354, .the shelf being thereu on released so that it returns to its retracts position as the finger 365 asses over the center of the shaft 276. At't 's point the can is in the position in-- dicated in dotted lines in Figure 3, the plate 322 being retracted as above pointed out to free the same from the upper surface of the can.

As the carrier turns down after passing the center of the sprocket shaft, the continued engagement of the roller with the end of the cam moving in an arc, forces the can to be moved entirely upon the rollers 353 and 354 from the dotted line to the full line position (Figure 3). p

A pair of supports 366 and 367 are mounted upon the supports 30 and 31 in Y which is journaled a shaft 368 having mounted thereon a pair of arms 369/and 370 provided at their ends with folding blades 371 and 372. Upon one end of the shaft there is provided a lever 373 pivotally connected to the end of a bar 374 extending through an opening 30 in the support 30, and provided at its other end with an elon gated slot 375 engaging the shaft 306 and provided at each end of the said slot with rollers 376 and 377 riding upon a cam 378 provided'on the said shaft, rotation of the said cam adapted through the lever and bar connection to swing the arms 369 and 370 causing the blades to engage the upper projecting portions of the wrapper and fold the same down upon the ends of the can as shown in Figure 19.

Two shafts 379 and 380 are journaled in the standards 347 and 348 and are provided with airs of tucker arms 381, 382, 383 and 384 dlsposed at the outer sides of the blades 371 and 372. Upon the ends of the said shafts there are provided intermeshing gears 385 and 386, and upon the extended end of the shaft 380 there is mounted a lever 387 (Figure 4) pivotally connected to the end of a bar 388, the said bar being provided at its other end with a slot 389 engaging a stud shaft 390 provided upon the support 344, rollers 391 and 392 being provided at the ends of the said slot which ride upon a cam 393 their ends engage-the projecting side porcally disposed post 397 havmg a horizontally bent up er portion 398 provided at its end with a p unger head 399 having spaced contact lugs 399 adapted to firmly engage the upper side of the can as the 0st descends. Reciprocation of the post is. rought about by means of a link 400 connecting its lower end with. an arm 401 provided upon a rock shaft 402 journaled in the supports 343 and 344, the said rock shaft 402 being provided at one end with a lever 403 pivotally connected to the end of a bar 404, the other end of the said bar being provided with a slot 405 engaging a stud shaft 406 provided upon the support 343, rollers 407 and 408 being provided at the ends of the said slot which ride upon acam 409 provided on the shaft, the said shaft being rotated by a gear 410 provided thereon and meshin with a pinion 411 provided on the en of the sprocket shaft 276.

- As the plunger head descends, it forces the can downwardly between the rollers 353 and 354 at the same time folding the lower projecting portion of the wrapper upwardly and pasting the same upon the folded upper and side portions as, indicated in Figure 23. As the can passes from between the rollers, it may drop upon a suitable chute (not shown) to convey the same away from the machine.

M ;1 improvements provide 'a machine whic may be operated with relatively great speed in which cans or other suitable articles may be wrapped in a clean, neat uniform manner. The imparting of'the paste to the wrapper and the handling of the pasted wrapper in connection with the can or other article is such that the workingparts of the machine will not come in contact with the paste and therefore will not impair the efiiciency thereof by becoming gummed with the paste.
